3. Mechanical Equipment
Defects in the mechanical components can generally be identified from the following;
• High vibrations
• Noise
• Overheating
• Inspection
Vibration may take place due to loose nuts and bolts, under - tensioned belts. damages in the turbine and
worn out bearings. Tighten up loose nuts and bolts. Check the turbine and see whether it is damaged or
loose. If there is a problem with the bearings they may have to be replaced with the help of a competent
technician. Worn out bearings can be identified using a long screw driver as shown in drawing below.
Checking the bearings for Vibration
A smooth sound while running indicates that the bearings function smoothly while a coarse or sharp
sound indicates that the bearings have some problem.
